Where are my Cells ?!
 
Hay all,
im trying to generate a simple cone-cyl simulation. here is my geo file:

__________________________________________________ ___________
l1 = 0.05;
l2 = 0.01;
n=10;
Point(1) = {-0, -0, 0,l1};
Point(2) = {0.4, -0, 0,l2};
Point(3) = {0.6, 0.1, 0,l2};
Point(4) = {1, 0.1, 0,l2};
Point(5) = {1, 0, 0,l2};
Point(6) = {1.3, -0, 0,l1};
Point(7) = {1.3, 0.4, 0,l1};
Point(8) = {0, 0.4, 0,l1};
Line(1) = {1, 2};
Line(2) = {2, 3};
Line(3) = {3, 4};
Line(4) = {4, 5};
Line(5) = {5, 6};
Line(6) = {6, 7};
Line(7) = {7, 8};
Line(8) = {8, 1};
Line Loop(9) = {7, 8, 1, 2, 3, 4, 5, 6};
Plane Surface(12) = {9};

Extrude {{1, 0, 0}, {0, 0, 0}, Pi/2} {
Surface{12}; Layers {n}; Recombine;
}
Extrude {{1, 0, 0}, {0, 0, 0}, Pi/2} {
Surface{44}; Layers {n}; Recombine;
}
Extrude {{1, 0, 0}, {0, 0, 0}, Pi/2} {
Surface{76}; Layers {n}; Recombine;
}
Extrude {{1, 0, 0}, {0, 0, 0}, Pi/2} {
Surface{108}; Layers {n}; Recombine;
}

Physical Surface("inflow") = {124, 28, 60, 92, 25, 57, 89, 121, 75, 43, 139, 107};
Physical Surface("wall") = {64, 32, 96, 128, 68, 132, 36, 100, 71, 39, 135, 103};
Physical Volume("vol") = {2, 1, 4, 3};

__________________________________________________ _

after i 3D mesh it and convering it using gmshToFoam, fixing the boundaries etc., loading the mesh using paraFoam, the inflow and walls apears great.
However, there are no inside cells.
It seems that the msh file does now contain the "vol" cells.

what am i doing wrong ? im sure its a no brainer

ps.
when trying to view the mesh in enGrid im getting the same problem.

Please HELP :confused:
